A sound wave is observed to travel through a liquid with a speed of 1380 m/s. The specific gravity of the liquid is 1.5. Determine the bulk modulus for this fluid. EN= 2.84 N/m²

If the fluid is contained in a long, narrow vessel so it can expand in essentially one direction only, show that the effective coefficient linear expansion a is approximately equal to the coefficient of volume expansion b?
